Techstack: Ubuntu/Debian, NGINX, PHP5FPM ( I will assume that you have these installed and nginx is talking to php5fpm)

Supposed you have a php application that needs to do different things based on a fastcgi_param variable, but you want to set a different variable based on another variable in nginx (like http hostname).

The nginx http_map module is the answer, but it may not be immediately obvious how to use it.

UPDATE: 2015-04-21 zfsonlinux update from 063 to 064, my zfs volume automounts. I tried getting the later versions of the pve kernel to work with zfs without any success. You are stuck with 2.6.32-26-pve.

This is a quick script to add to your fabfile, python fabric arsenal. This will check your server openssl version, and it does not match the current “safe” version, the script can either update or notify you in stdout.

UPDATE: This is a quick and dirty hack. REGEX for version check needs to be cleaned up.
